Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If discharge electrodes and counter electrodes are disposed parallel to each other in the electric dust collecting device, then corona discharge can be generated for dust collection, but the structure becomes complex and cleaning becomes inconvenient
Solution Approach 1:
The patent removes the counter electrode component from the traditional parallel electrode structure, extracting only the necessary discharge electrode and ground-connected collecting electrode configuration. This simplifies the overall structure while maintaining the corona discharge dust collection function.
Solution Approach 2:
The collecting electrode serves dual functions: it acts as both the collecting surface for charged particles and the ground reference for corona discharge, eliminating the need for a separate counter electrode. This multi-functionality reduces structural complexity.
2Ease of manufacture
If discharge electrodes and counter electrodes are disposed parallel to each other in the electric dust collecting device, then corona discharge can be generated for dust collection, but cleaning convenience deteriorates due to accumulated pollutants
Solution Approach 1:
The patent divides the dust collecting device into two separable units: a first filter unit containing discharge electrodes and a second filter unit containing collecting electrodes. This segmentation allows the second filter unit to be independently removed and cleaned, significantly improving maintenance convenience.
Solution Approach 2:
The patent extracts the collecting electrode assembly into a separate, removable second filter unit that can be independently accessed for cleaning. This extraction enables users to easily remove and clean the pollutant-collecting component without disassembling the entire device.
3Productivity
If the number of discharge electrode plates is maximized in the same surface area, then electrical charging rate is enhanced, but the structure becomes more complex
Solution Approach 1:
The patent merges multiple discharge electrode plates into a single integrated first filter unit assembly. This combining approach allows multiple electrodes to be arranged efficiently within the same surface area to maximize charging rate, while the unified assembly reduces structural complexity compared to separate electrode components.
